Marty is still finding his bearings when he accidentally disrupts his parents’ meeting, threatening his own existence. Fortunately, he locates the younger Doc and together they plan to reunite Marty’s parents and send him back to his own time.

After 27 years, Back to the Future is a double nostalgia fest – the ’80s music, slang and pop culture are as much of a treat as their ‘50s equivalents. The humour’s still fresh – I especially loved the UFO riffs and theStar Wars and Star Trek mashup.

The improbable relationship between Doc, the stereotypical mad professor, and Marty, the feckless adolescent, is as endearing as ever. And the souped-up DeLorean time machine and its flux capacitor are entrenched pop-culture symbols – because even if time travel might have disastrous consequences, as Doc says, why not do it with some style?
